Serine/threonine-protein kinase Sgk3 is an enzyme that in humans is encoded by the SGK3 gene.^[1][2][3]

Function

This gene is a member of the Ser/Thr protein kinase family and encodes a phosphoprotein with a PX (phox homology) domain. The protein phosphorylates several target proteins and has a role in neutral amino acid transport and activation of potassium and chloride channels. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.^[3]

In melanocytic cells SGK3 gene expression may be regulated by MITF.^[4]

Interactions

SGK3 has been shown to interact with GSK3B.^[5]
